(5)has;had
(1)本句是现在完成时,否定句需要在助动词后面加not,already 变为 yet,故填 hasn't finished yet。
(2)本句是 make sb do sth 结构,后面跟省略to的不定式,改为被动语态时需要将 to 添加上去,即 be made to do sth,故填 to do。
(3)根据 never been 可以推断 Gana's 为 Gana has 的缩写,never 表示否定,反义疑问句为“前否后肯”,故填 has she。
(4)used to 是固定搭配,表示“过去常常做某事”,改为一般疑问句需要用助动词 Did,故填 Did use。
(5)bought 是buy的过去分词,属于短暂性动词,和时间段 for two days 连用时,需要转化为延续性动词 has had。
本题考查句型转换,做这类题,不但要根据句意,选择正确意义的词、词组及句型,还要根据具体语法和语境,选择适当的时态、语态及使用正确的词形。
